To all whom it may camera."

Be it known that I, ALBERT DAY, a subject of the King of Great Britain, residing at 53 Winsham Grove, in the county of London, England, have invented certain new and useful Improvements in or Relating to Machines for Making and Filling Packets, of which the following is a specification.

This inventionrelates to machines for making and filling packets, of the kind comprising a folder termed the fourth folder, having consecutive horizontal and vertical movements, a stationary mould slotted to give passage to the said folder, and a vertically movable funnel having a hollowstem or. former to which the charge oftea or other material to be packed was delivered while the bag was being made thereon, the operations of making and filling one bag proceeding simultaneously with the operations of closing and ejecting the preceding filled 1 According to the presentimprovements the former is vertically reciprocable, moving with the said fourth folder, and the slotted mould is stationary and has a movable bottom to allow the folder or othermoving part to carry or push a filled packet down to an ejector platform situated atfa lower level. v r t i In order that the said invention may be clearly understood and readily carried into effect the same will now be described more fully with reference to" the accompanying drawings illustrating the parts of the machine with which the present invention is concerned; j I I v Figure 1 is a front elevation.

Figure 2 is apartial side elevation.

Figure 3 is a plan taken on the line 33 in Figure 2. a V Figure 4 is a plan taken on thelinefl44 inF1gure2. r

Figure 5 is a plan taken on the line 55 in Figure 2.

The reference numeral 11 indicates the framework of the machine,-in which are secured pillars 250,251, connected together by a crossbari259 (Figure 1). In the frame 11 are mounted rotary shafts 24 and 136,

and stay rods 58, 141,and 217 (Figure 2) are utilized for the support of movable parts of the machine. A rammer 260 (Figure 1) is carried in a bracket 252 adapted to be reciprocated on thepillars 25 0, 251 by cranks 255,256 on the shaft 136, which cranks are connected by ,rods 257, 258 with the'said bracket 252. f t

The former A is carried in a bracket a vertically reciprocated on the pillars 250, 251, by a rod a which receives its motion from a lever 01? pivoted on the stay rod 141 V and carrying a bowl a engaginga cam 11 on the rotary shaft 136. t I v l to the machine frame by a bracket 6, and its wall at b (Figures 2 {and 3) is slotted to give passage to the fourth folder. Itsfloor or bottom plate 5 which has a T shaped slot (see Figure is periodically withdrawn and re turned to the position shown by meansflof a reciprocating rodb actuated by a lever b pivoted on the stay rod 141, this lever carrying a bowl 6 engaging a cam on the rotary shaft 136. Instead of having a sim- 'ple backward and forward movement, the

mould bottom plate maybe pivoted and swung .to one side when its absence from the mould is required, or it may be made intwo halves arranged to slide apart in diametrically opposite directions, or the two halves may be separately pivoted and arranged to open out or swing on their pivots away from each. other. I

The fourth-folder'is T shaped in plan comprising a shank C having upper and lower lateral extensions 0' (Figure 3 and 0 (Figures 1 and 2) which provide a broad front at each of the operative partsof the folder, namely the upper part which comwhichcompletes the folding of the top of the packet in the mould, on the forward stroke of the folder. This forward stroke is accomplished by a two-armed lever 213 pletes the folding of the bottom of the filledbag under the former and the lower part link 214;: The foldershank C hasa down- -ward extension 218 connected with a threearmed lever 216 pivoted on the stay rod 217 and carrying a bowl 220 engaging a cam 208 on the rotary shaft 24; a spring 221 7' holds thebowl 220 against its cam. This cam 208 thus eflects a downward stroke of the'folder, this being timed to occur immediately after the last folds have been made by the forward stroke ofthe folder, and to coincide with the downward stroke of the former obtained by the action of the cam a as aforesaid. V

A lower blade or foot D may be secured to the shank C of the folder as shown in Figures 2 and at, the said blade D therefore partaking in the movementsof the folder. Alternatively this blade D may be moved by separate mechanism, but it must follow the movements of the folder toperform the functions hereinafter described.

The ejector platform E (Figures 2 and 5) is slotted at e to allow the blade D .to pass througlrit and travel below the path of the ejector F when the latter is advanced to push a packet off the platform'E into the ejector trough e lVhen by the lifting of the rammer 260 the charge of tea or other material has been delivered into the former A so as to rest on the first fold of the bottom of the bag, the second and third folds beingthen made, the fourth folder advances from the position shown in Figure 2 so that the part (7' thereof completes the folding of the part of the bag bottom projecting below the former A and the part c completes the folding'of the top of the packet in the mould B, the blade D simultaneously advancing into the slot in the mould bottom plate 6 under the packet. Hamming of the charge in the bag may be performed before, during, or after the transfer of the filled bag to the mould, which transfenis efiected by the former, folder, and blade D descending together, while the plate 5 is withdrawn to allow the completed packet from the mould to be carried down between the part0 and blade D. The plate 6 then advances over the top of the part c withits slotted portion passing at each side of the narrow central part C of the folder, so that the said plate 6 is ready to support andcontrol the bottom of the filled bag when the upper part 0 of the folder has passed'through the T-shaped slot in the plate N, at which time the blade D has also passed through the slot 6' in the ejector platform E, leaving the completed packet on the ejector platform. The folder and blade D are then drawn back clear of the mould and packet, andrise to repeat their forward stroke, while the ejectonF pushes the packet off the platform E into the ejector trough c and the former rises again to receive the next wrapper for making another bag, the rammer remaining in the former until the rammer has to be further lifted to admit the next charge. 7

rilternatively the ejector platform E may be arranged to rise to receive the packet from the mould, and descend with thesaid packet to the position in which the packet is removed to the trough e form located below said mould.
